Where, K is the photon energy of the incident radiation; Q corresponding charge amount generated by the detector; k for the response parameters of different types of energy detectors. The amount of charge is proportional to the incident ray energy 3VROHS meter three-valued, it is characterized by measuring the amount of charge available information measured elements. Characteristic spectral lines measured elements need to adopt certain excitation source to get. Currently excitation source conventionally used mainly ray tube and isotope excitation sources. In order to obtain qualitative and quantitative information of the sample, in addition to the spectrometer, but also must adopt certain sample preparation techniques, and the strength of the obtained spectral correlation analysis and data processing. 3 Technical Specifications Edit Elemental analysis range from sulfur (S) to uranium (U) Elements of harmful elements in the range of 1 PPm to 99.99% RoHS Directive (restriction Cd / Pb / Cr / Hg / Br) detection limit up 1PPM ; 6 standard response RoHS Directive To help Chinese enterprises to succeed across the environmental directives (ROHS Directive) previously issued by the EU set export threshold Recently, AQSIQ and CNCA jointly announced the six spectrometer ROHS standard detection methods These standards will be held on January 18 next year to implement, and also announced a 18 bear electrical and electronic products, toxic and hazardous substances detection task units. AQSIQ spokesman Liu Zhaobin said the release of these standards is satisfied gifted ROHS detector 3000 will help standardize detection methods of the testing room, more conducive to Chinese products exported to the EU, and the impact of the international standards and other national standards making.
